A friend lent me Jodi Picoult's My Sister's Keeper after a brunch conversation briefly touched on child leukemia patients. The book is about a girl whose parents had her so that she could be a donor match for her older sister. The girl decides to hire a lawyer to file for medical emancipation so her parents won't force her to keep donating for her sister. Though the book jacket and several reviews billed it as a tale of sisterhood and parenthood, it's also a story about ethics and legal consent.
The story is told from half a dozen different viewpoints, from the younger sister to the parents to the lawyer. Not only is every other chapter a different narrator -- but every narrator gets their own font! A lot of the book consists of flashbacks, and overall it was a really quick read.
The ending was a little predictable (though the exact details weren't), but still really sad, and I ended up sniffling and tearing up a bit.
